EC-320 < DTC/CIRCUIT DIAGNOSIS > [QR25DE] P0444, P0445 EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE Is the inspection result normal? YES >> GO TO 3. NO >> GO TO 2. 2. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE POWER SUPPLY CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect IPDM E/R harness connector. 3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and IPDM E/R harness connector. 4. Also check harness for short to ground. YES >> Perform the trouble diagnosis for power supply circuit. NO >> Repair or replace error-detected parts. 3. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE GROUND CIRCUIT 1. Turn ignition switch OFF. 2. Disconnect ECM harness connector. 3. Check the continuity between EVAP canister purge volume control solenoid valve harness connector and ECM harness connector. 4. Also check harness for short to power. YES-1 >> With CONSULT: GO TO 4. YES-2 >> Without CONSULT: GO TO 5. NO >> Repair or replace error-detected parts. 4. CHECK EVAP CANISTER PURGE VOLUME CONTROL SOLENOID VALVE OPERATION With CONSULT 1. Reconnect all harness connectors disconnected. 2. Start engine. 3. Perform “PURG VOL CONT/V” in “ACTIVE TEST” mode of “ENGINE” using CONSULT. 4. Check that engine speed varies according to the valve opening. YES >> GO TO 6. NO >> GO TO 5. 5.
